DHCP service is used to dynamically assign the IP address, gateway, domain name server and other information to the workstation client, eliminating the cumbersome manual setting of the client. When there are many clients, using DHCP to configure the network can greatly reduce the administrator’s work!
Enable the DHCP service of the LAN port to allow the intranet hosts automatically obtains the IP addresses.
If closed the DHCP function, the intranet hosts cannot automatically obtain the IP address and need to configure the IP address on the hosts manually.
Notes of DHCP configuration
If there are massive hosts, we recommended reducing the lease time to 30~45 minutes to avoid exhausting the address pool;
If using in an Internet cafe, we recommended to turn off the DHCP configuration;
The internal network has access to the wireless AP. It is recommended to connect the AP to another LAN port by configuring an independent multi-LAN to physically isolate the wireless network;
Multi-LAN extended DHCP establishment prerequisites must have independent multi-LAN, ie [advanced setting] == “[elastic port], from which to generate independent multi-LAN, please refer to [elastic port];
Multi-VLAN extension DHCP establishment prerequisites must have independent multi-VLAN, ie [advanced setting] == “[VLAN], from which to generate independent VLAN, please refer to [VLAN].
The static lease is used to assign a fixed IP address and host ID to a DHCP client. Only legitimate hosts can connect, and the interfaces must be non-dynamically configured.
Use the Add button to add a new lease entry. MAC-address authentication host, IPv4-address assignment address, hostname assignment identifier.
In short: for a fixed mac [fixed computer] (the computer’s mac address is uniquely fixed, unless artificially modified), assign the specified IP address.
Static Batch Lease
Add a batch of static leases. The format of each line is IP MAC, IP address and MAC address. Separated by spaces. Press Enter for each line. Such as: 192.168.1.111 00:0e:0f:1d:1c:eb
Click the [Detect] button to check if there are other DHCP servers in the intranet. The detection process will takes a few minutes.
